Back in the day, SE used to work just as well on a phone browser and on a laptop.
Then some time ago I found that from an SE site I couldn't click on the links that show up when you click on the car window in the up right corner next to your badge count:
Or when you click on the star cup next to the car window:
BUT I still could click on them from the main site, https://stackexchange.com/
So I got into the habit of taking a sneak peek into hot questions with my morning coffee.
Now the feature is broken even from the main site: I can click the car window to get an overview of comments, but I can't click on a particular comment - the same goes with achievements.
Is my phone really just getting old? I'm using a Samsung Galaxy S2 for the record.
I just found out that everything works perfectly on SE sites where I do not have an account. On the sites where I'm active, even clicking the icons won't show the lists now. On the main site, it's halfway: I will see the list but I can't click on the items.
